Spent many years experimenting shooting 22 centerfires in "wet paper" media, water jugs, chunks of meat to help figure out what was a good bullet for fur varmints....then took them to the field and shot coyotes, fox, coons and cats....found out quick stay away from any bullet that has a heavy copper base ....under 2800 fps is maximum velocity that's needed....lighter weight bullets are better if you stay off bone on entrance....

Speer 50 gr. "TNT" hollow point....keep them under 2800 fps ....rare to get one to exit...
